Problems solved by technology

[0004] However, motors mounted next to the drum can cause placement difficulties or constraints during installation, as the motors need to be located in specific sectors so as not to interfere with falling cables
On the other hand, lifting winch systems are very expensive to assemble

Embodiment Construction

[0026] As shown in the figures, the hoisting winch assembly 1 comprises two axially parallel drums 2 spaced apart from each other, which drums can be constructed in the usual manner per se with respect to their basic structure, and can in particular consist of flanged wheels with grooves. Roller body. On the edge portion of the end face, the drum 2 may also comprise a non-grooved cylindrical portion forming a reserve if longer ropes are to be pulled up. In a manner known per se, in order to be able to stably raise and lower the lifting spreader for picking up the containers, two ropes can be drawn from each drum 2 , as can be the case, for example, in gantry cranes or container cranes .

[0027] As shown, in particular, the drums 2 may be arranged coaxially with each other.

[0028] Each drum 2 here is driven by an electric motor 3 , and the motor 3 is drivingly connected to only one drum respectively via a separate gear transmission mechanism 4 or 5 of a transmission assemb...

Abstract

The present invention relates to a hoisting winch assembly comprising at least two preferably axially parallel drums spaced from each other axially, which can be driven in synchronism with each other by two motors via a transmission assembly. The invention furthermore relates to a crane, in particular a gantry and / or container crane, with such hoisting winch assembly. According to the invention, the transmission assembly has at least two separate gear trains, so that each motor is in drive connection with one drum each via a separate gear train. As compared to a common transmission to which both motors are connected, the separate gear trains can be configured significantly lighter and smaller, as no longer the power of both motors added up, but only the power of one motor must be transmitted. Nevertheless, high hoisting powers can be provided on the whole, as each motor must drive only one drum.

Description

technical field [0001] The invention relates to a hoist winch assembly, preferably comprising at least two axially parallel drums, said drums being axially spaced apart from each other, capable of being driven synchronously with each other by two electric motors through a transmission assembly . The invention also relates to cranes, in particular to gantry and / or container cranes having such a lifting winch assembly. Background technique [0002] Document DE 10 2009 050 584 A1 shows a container crane whose lifting device comprises two axially parallel drums spaced apart axially from each other, said axial being in the direction of the drum longitudinal axis, The two rollers may be driven by a driving unit provided at a central position between the rollers. The drive unit comprises a torque motor in the form of a multi-pole permanent magnet synchronous motor, which drives the drum via a cardan shaft, wherein a transmission driven by the cardan shaft and capable of reducing ...
